C4− carbide ligand in the trigonal prismatic environment of rheniums in [Re12CS17(CN)6]n− complexes

The electronic state of carbon in trigonal prismatic environment in [Re12CS17(CN)6]n− complexes with variable redox state n = 6 ↔ 8 was studied by molecular orbital method and electron localization function. The state is characterized by sp2-hybridisation and oxidation state −4. A weak long-distance interaction between μ6-С and μ2-S in the group [(μ6-С)(μ2-S)3] was discovered for n = 6, the interaction disappears for n = 8.
